Focusing on specific marker genes for phylogenetic identification/classification is one of the main categories of metagenomic sequencing. For this so-called targeted amplicon approach, the ribosomal small subunit RNA (16S rRNA) gene has emerged as the most commonly used marker. Further target genes may include other rRNA genes, the ITS region, COI, Rubisco or additional functional genes.
IMGM’s flexible metagenomics amplicon sequencing service offers the choice between experimentally tested primer pairs for different variable regions alongside the 16S rRNA gene (see graph below).
We also offer you a completely flexible choice for own primers depending on your targets and research aims. Our project managers will support you from custom Primer design to individualized bioinformatics.
Additional flexibility is provided by the possibility to step into the analysis pipeline at your most convenient starting point, e.g. start directly with gDNA, preamplified PCR products or even sequencing-ready libraries. If your project belongs to the category “off the beaten path”, IMGM has a long-standing expertise with scientific consultation and custom project design for metagenomics analyses.
For 16S/18S and ITS we offer the analysis of microbial composition, diversity and abundance with up-to-date bioinformatics software tools. OTU clustering and phylogenetic classification as well as further steps like calculation of alpha and beta diversity is carried out with a diligent view on data quality. This enables you to easily extract conclusions from your experimental data and to directly use our data to publish your results.
